LOCK DEVICE.

A Application filed June 15, 1922. Serial No. 568,378.

To all whom itma-g concern.

Be it known that I, BENJAMIN A. BOOTH, a subject of the King of GreatBritain, and resident of Odessa, in the Province of Ontario and Dominionof Canada, have invented certainnew and useful Improvements in LookDevices, of which the following is a specification. v

The principal object of this invention is to provide a new and improvedlocking means I for garage, barn or stable doors or the like, which willbe of very substantial construction and which will be so arranged thatit will be impossible toforce or jimmy the doors from the Outside.

Another object is to provid a locking means which will be actuated bythe forcehandle being controlled by alock of the so called cylindertype. I

. Another object is to provide means for adjusting the locking bar. todoors of various heights, and a further object is to provide means toadjust the lockingcatches to compensate for warping of the doors.

For the accompl'shment of these and such further objects aswill'hereinafter be apparent to those skilled in the art to which thisappertains, the invention consists in the construction, combination andarrangement of parts herein specifically described and illustrated inthe accompanying drawings, wherein is shown a preferredembodiment of theinvention, but it is to be understood that changes, variations andmodifications may be resorted to which iall'within the scope of theclaims hereunto appended.

In the drawing forming a portion of this specification.

Fig. 1 is an elevation of the inside of a pair of doors showing myinvention applied thereto.

Fig. 2 is a section on the line 22 of Fig. 1, and

. Fig. 5 is a detail showing the manner in which the actuating handle isconnected to the locking bar.

As shown in the drawings, the numerals and 11 indicate the doors towhich my invention is shown applied. Secured to the door, 10 at suitablyspaced points are the brackets 12, 13, 14 and 15. Slidably mounted inthese brackets is a composite locking bar which consists of the endmembers 16 and 17 preferably of rectangular cross section which areslidably mounted in the brackets 12 and 15 respectively. Secured to theend members 16 and 17 respectively, are 7 the rods 18 and 19, which areprovided with right and left hand threads to engage with the tappedholes of an adjusting member 20, said member. being preferably formed toprovide a handle or grip as clearly shown in Fig. 2 of the drawing.

The end members 16 and 17 are provided with hook portions 21 and 22'respectively, the hook portion 21 being adapted to engage within arectangular aperture 23 in a keeper 24 secured to the door frame, while7 the hook portion 22 is adapted toengage with the keeper 25 secured tothe door sill.

The locking bar which is mounted upon the door 11 is slidingly mountedin the brackets 26 and 27, and comprises th end members 28 and 29, thelower ends of which are provided with tapped holes having right and lefthand threads respectively, and in which are secured the ends of aconnecting bar 30. The end member 28 is provided with a flattened end31, having the rectangular aperture 32 therein which is adapted toengage over the hooked keeper 33, while the end member 29 is flattenedas at 34 to engage with the keeper 35.

Secured to the connecting bar intermediate the end members is a collar36, having an arm 37 projecting therefrom towards the door 11, said armbeing bent at right angles to provide a portion 38 lying substantiallyparallel to the plane of the door. A longitudinal slot 39 is provided inthe portion 38, adjacent th end thereof and slidably receives a pin 40projecting from a connecting link secured to a sleeve 41 upon the outerend of which is secured an actuating handle or knob 42. The knob 42 ismounted upon the outer side of the door 11 and the interior of thesleeve 41 is provided with a spring lock of the so called cylinder typeadapted to automatically prevent the turning of the knobeXcept when thekey is in serted therein. Locks of this general type are common and wellknown and as the lock structure itself forms no part of the presentinvention, further description thereof is not necessary for the purposesof this application.

Each of the keeper members 24 25, 33 and 35, are provided withlongitudinal slots indicated by the numeral 43 to permit the adjustmentof the keepers to compensate for any warping of the doors or door frame.Lock nuts 44 are also provided to secure the parts of the bars inadjusted position. The members comprising the locking bars areconstructed of metal and are of sufliciently large cross-sectional areato afford sufficient weight to the locking bars to cause them to dropreadily into engagement with the keepers. The substantial size of thelocking bars is also such that added security is given, making itimpossible to spring the bars out of engagement.

It will be noted that the inner lower ends of the hook members 21, 22and 34 are tapered and that the cooperating keeper members are alsotapered to cause the locking bars to be raised over the keepers when thedoors are swung to closed position.

The bottom keepers 25 and 35 are of greater transverse width than thecatch portions 22 and 34, thereby making it impossible to engage thebottoms of the locking bars and to raise them by inserting a rod underthe doors from the outside.

lVhile I have illustrated my invention as applied to doors of the hingedor swinging type, it will be understood that it could be readily appliedto sliding doors by merely turning the locking bars at right angles tothat shown in connection with the swinging doors herein.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A device of the character described comprising a locking bar having apair of end members provided with catches, means to secure said lockingbar slidably to a door, means to adjust said end members longitudinally,keepers mounted on the door frame adapted to be engaged by said catcheswhen said door is closed, a sleeve mounted upon said locking bar havingan arm projecti-ng at right angles therefrom, an actu ating handlemounted on the outer side of said door and means connecting said handleand projecting arm. p

2. A device of the character described comprising a locking bar having apair of end members provided with catches, means to secure said lockingbar slidably to a door,

means to adjust said end members longimembers provided with catches,means to slidably mount said locking bar on a door, a member carried bysaid bar and having a projecting portion, an actuating handle carried bysaid door. a connection between said handle and projecting portionhaving a movement relative tothe latter and capable of actuating saidlocking bar when said handle is operated and keepers mounted on the doorframe and capable of being engaged by said catches when said door isclosed. 1 p

4. A device of the character described in cluding a locking bar having apair of end members provided with catches, means to slidably mount saidlocking bar on a door, a member carried by said bar and having aprojecting portion, an actuating handle carried by said door, aconnection between said handle and projecting portion having a movementrelative to the latter and capable of actuating said locking bar whensaid handle is operated and keepers mounted on the door frame and.capable of being engaged by said catches when said door is closed, saidkeepers being of a greater width than said end members and provided witha shoulder lying between said catches and the door to prevent saidlocking bar from being raised from outside said door.
